Spoiler: it is late and I am tetchy and this is overly harsh. someone responded to my friend's fb post asking for ideas on how to work toward reclaiming and/or rewilding the one million golf courses that take up over half of our city's greenspace with 'nationalise the land!', and when they said 'yes! how?' he responded with 'Good question.' and then an apparently earnest answer that first we'll need a socialist workers' govt, so we need to start establishing a revolutionary movement & party. dude!! this is a post about reclaiming or establishing common land by hook or by crook, you do not need to convert people here, a good example of 'organising around shared demands' as you suggest would be literally the thing that is happening in the comments around you - with concrete ideas of who to reach out to and how to start, unlike yr comment where the issue at hand seems like a total afterthought. He meant well, we're on the same sides of the issue and probably most of the ones I think are important, I don't know the guy, maybe I'm missing something he was trying to say, I am guilty of worse high-handedness. Argh, though.
